Within Properties > Jaspersoft Studio > Compatibility the Source .jrxml Version dropdown does not include all past JasperReport library versions. For instance, it jumps from JasperReports 6.5.1 to JasperReports 6.10.0 skipping versions 6.6.0, 6.7.0, 6.7.1, 6.8.0, 6.8.1., 6.9.0. For users that have built an application that uses one of the skipped JasperReport library versions - what should they set the compatibility version to when building reports within JasperSoft Studio?
